Potentially poor sound quality with carputer vs. HU

Before I begin ordering my carputer, I want to clear this issue up.
I'm worried the carputer won't sound as good as a typical Alpine head unit with 4 volt outputs.

I plan on running an epia M10000 with an Audigy 2 card. This will tie into a fosgate power amp. From what I have read the Audigy can only output 2 volts to the amps vs. the alpine's 4. Is there going to be a huge difference between the two, it seems like there will be? Running both a carputer and head unit or 5.1 equalizer like the Alpine PXA-H700 is out of the question due to price.

The output of the card is not what determines the output of the amp... you may as Frodo said need to adjust the gain on the amp a lil higher but the output of the audigy is quite sufficient to sent a quality signal to the amps

If you can, try and use the Audigy NX USB or Extigy USB, you don't get all the EMF noise that sometimes happens with internal cards. The signal is purely digital until it hits the box *outside* the PC, and you can run very short RCA's. The gains on my amps are ALL the way down, and it outputs 2.5v to the RCA's. With the gain's so far down, they are really clean and quiet. Need USB 2.0 for the best sound though, and a good 5v, 1.25a+ powersupply (search for my other posts on how to make one for around 15$ in parts).

I had no luck with an internal SBLive! from way back when, there was always this "pc" related hum when it accessed the hd, or processed (significant noise at full volume). YMMV!

Still wondering though, does anyone have any noticeable computer noise through their internal or onboard soundcards? Phono jacks aren't shielded very well, what are you all doing to get the signal to RCA?

I used one piece phono to RCA adapters, gold series from radio shack, is the spacing too tight on the newer audigy's (internal) to use these?

Just a side note, make sure your computer is grounded, as soon as I grounded my computer to the car, the sound was alot better.
